This paper explores how admissions tests are used in different higher education systems around the world. This is a relatively new area of research, despite the fact that admissions processes are a key component of university practices and given the ever increasing globalisation of higher education. This paper shows that aptitude and achievement tests, for example, are used in many developed countries. In some of them, a specific test is nationally instituted and generalised; consequently, the function of the test is well embedded in the education landscape of the country. Elsewhere, tests exist but are administered in an ad hoc fashion with little consistency across the sector. This paper provides an important reference tool for national systems and individual institutions interested in examining their position within the realm of international practice in the utilisation of admissions testing for university selection.
